Frances McDormand had her Oscar engraved with her name at the Governor's Ball before it went missing

Los Angeles police had said that Mr Bryant was a ticket holder for the Governor's Ball, which is the official formal dinner after the ceremony.

Video showed a tuxedo-wearing Mr Bryant leaving the party holding the statuette and saying: "We did it!" His lawyer argued in previous hearings that Mr Bryant did not intend to keep the award, which was quickly recovered and returned to McDormand.

It was her second Oscar, 21 years after she won one for her performance in Fargo.
